The Dakar Peninsula (Senegal): geoheritage and vulnerability to flooding and coastal erosion
Year: 2020
Type: article
Abstract: The geoheritage characteristics of the Dakar Peninsula (Senegal) are studied in order to better document the causes of catastrophic floods on this site since the mid-1980s.It appears that the suburbs of the Senegalese capital (Dakar) are highly vulnerable to floods.Apart from the current climate change, this vulnerability depends on the geodiversity of the peninsula, which has been shaped over time by numerous geological phenomena: erection of the Cenozoic sedimentary horst of Dakar, numerous Cenozoic and early Quaternary volcanic episodes , and Late Quaternary sand dune deposits that shaped the geomorphic architecture of the Cap Vert peninsula.The city of Dakar erected partly on the sedimentary horst and partly on the basalt basement is less exposed to floods, unlike the suburbs erected on sandy substrate dotted with many lakes and depressions whose altitude often negative.
